i257m no lte only h+ - Galaxy S 4 Mini Q&A, Help & Troubleshooting

EDIT: turns out ATT used a 3g only sim car when they activated my account. LTE is up and running smooth on my phone now!
I ordered a Rogers i257m to use here on att in the states. After setting it up I only get hspa+ and no lte even with updated apn settins.
First thing I did was rooted it with vroot, updated superuser.
After that I threw on twrp through odin.
Then I used regionlock away app to unlock the phone. (this is the part im skeptical about)
All was well while I was playing with stock rooted rom, it shows me on 4g (h+) and I was happy with data speeds and getting used to everything. I never thought about questioning if I were on lte since it said 4g.
I flashed slimkat and carbon 4.4's and both get only HSPA no plus and no lte. bluetooth also does not work on those roms. I tried flashing both 4.4 aosp kernels with no luck there.
SO I figured id go to sammobile and download the stock 4.2.2 image from rogers and toss it through odin. rooted with the rootkit this time and flashed twrp back after, still same problems.
WHAT GIVES?? I feel like I have tried everything possible, does anyone know any tricks to get me up to at least 4g and bluetooth on aosp!?
hours on the phone with att and they give me the answer that if teh phone is not an att phone origianlly you cannot get lte as it is not recogfnized as being compatible in their sytem.. i call bs, anyone else getting lte?

I got an unlocked Telus SGH-I257M (I presume it was unlocked with a code) and it worked fine once I changed the APN. It could be a problem with regionlock away but I'm not sure.

yeah thats what im guessing, but I have no clue how to undo what that app did and how to unlock it any other way
you can confirm you get lte though?

Yes, it does get LTE for sure. I believe regionlock away has an option to revert the changes it made. In order to unlock your phone the normal way you'd need to buy an unlock code. As I said I bought the phone unlocked already so I can't really help with that..
EDIT: Also keep in mind I an talking about LTE on the stock ROM. Other ROMs for the I9195 could have issues with the I257 variant phones?

An update to the thread. I was able to get LTE after borrowing an ATT s3 from a friend to add to my account and take to the store. they narrowed it down to a 3g sim card and not an lte one... go figure.

Bell i317 LTE APN help?

I just recently bought a locked Rogers Galaxy Note II i317M and unlocked it using cellunlocker(dot)net; however, I am not getting a LTE signal on Bell for some reason — it's always just "4G".
I talked to a rep and he said that it should work since im in a LTE covered area. He also said that he can't help me further since I didn't buy the phone from Bell .
Anyone know what's happening here? Did the unlocking mess it up? Is that even possible?
I'd really appreciate any help. Thanks.

What are your APN settings?
Bell does not have a different apn for lte and hspa. After flashing some at&t roms, I am not getting lte at all. But the stock room is okay .
I'm on Rogers and couldn't get on LTE. It turned out to be my old SIM. Rogers replaced it and voila, LTE. Not sure if Bell has a similar issue with older SIMs or not, but maybe it's worth a try.
i flashed the Rogers modem. Works now.
Yeah check your apn settings and post them here

You don't need an LTE plan on Bell.

Sometimes changing the apn to proxy.bell.ca instead of pda.bell.ca would fix the issue. . Although tried both ways on my SGN2 - both worked out well..

lte not working for me
hi guys i recently flashed miui for my note 2 and noticed im only getting 3g, my APN settings look the same and ive also played around with them but always end up with either no internet or only 3g. any suggestions?
As a canadian multi-carrier cell phone salesman you do need a data plan, sim, and phone all to be lte enabled for lte service. If you are on a plan roughly two years or older you most likely did not get upgraded to lte data. This sounds like your issue here, and you would have to go talk to your corporate to have the plan changed over. I'm not sure if its a personal under a corporate (this case changing should be easy) or a giant bucket plan, in which case good luck.
Rogers is the only canadian carrier to have an lte APN.
and lastly your bell micro sim should clearly be labeled LTE, and for others FYI Telus sim cards should be V31, and rogers I believe its B010 if memory serves me right.
On the note 2 lte is already a default setting if already enabled.
well i guess then miui for the note 2 is not an lte rom because ive checked and rechecked my apn settings, and i have all the above that u mentioned, the stock rom (4.1.1) had lte but when i flashed miui all im getting is 3g.
apn settings all blank i317m
I did something in odin.
I am on 4.3 official firmware but I have no mobile data. I checked my apn settings and virtually all settings are blank. Not set.
Help please
Thanks

LTE on Canadian Note2

I was wondering if there is a way to get LTE enabled on a canadian Note 2 now that T-mobile enabled LTE on their version. I'm on the videotron version running on Fido/rogers
Hello fellow canadian, I flashed just the new modem, enabled lte though *#2263# menu. And my data speeds are great. I am on Telus.

So that makes at least a second LTE-enabled T889V out there. Good. I'll PM you my draft guide, maybe we can compare notes (pun intended) and have a proper procedure to publish. I haven't made anything too public because either my would-be testers changed their minds, or did not update me at all.

So you reflashed the LTE modem and it is running fine? or you went back to the HSPA+ one. Right now I am on T889UVALL4. To scared to flash back the LTE one. Maybe when I get more time to deal with a loss of imei again I will try the LTE one again.
Update: Flashed the Tmobile LTE modem again and is running fine thus far.

Not much of a guide really out there. I flashed the tmobile modem for lte, lost my imei, managed to restore it and now have lte. Although I am now stuck with a tmobile modem. If I flash a t889v modem I go into a boot loop. Think it would be best to wait until there is a proper way of getting it done.

are you on a canadian carrier? I want LTE for bell on this phone.... it doesnt matter if i lose the wind, videtron and moblicity compatability as only videotron is available where i live, and they're no good for me.
Yes im on Telus. Check your pm.
You don't even have to lose AWS DC-HSPA as I found out last December after dropping by a Videotron kiosk. This was further confirmed by Sjravi's tutorial to enable AWS on the I317.
i have just 1 question, is your battery life the same after you enabled LTE? now i can go about 1-2 days with heavy usage on my phone without having to charge it. just wondering before i jump in....
I've modded my phone early enough that I don't have much basis for comparison, but I have no issue going through a heavy usage day with plenty to spare. Trying two might be pushing it, but I've done it with low usage days. YMMV.

With just the lte modem I have not noticed much if any battery drain. Am getting some crazy fast download/upload speeds...
and it shows LTE next to the signal bars?
No I dont have the lte icon, not included in this rom. But when I go to about phone status It shows lte. Getting 42mbps down and 21 up

[Q] AT&T i747 unlocked using T-Mobile

First of all i wanna say, you all do an amazing job with all of this. So ive been looking around the forums and i cant find an answer to my question, so i will post and wait for replay. i have the at&t version (i747) of the gs3 and had updated to 4.1.1 via kies. early march i found a post on your forums about sim/carrier unlocking and tried it out. it worked w/o any problems, so i headed to t-mobile to jump on their monthly unlimited 4g plan. installed sim and had no problems. all functions work: calls, im, sms, mms, data (edge, 3g, and HSPA+), everything. on march 17th, i decided to try out a custom rom. i odin rooted my phone with cwm then tried out [ROM][4.2.2][STABLE] LiquidSmooth v2.1 - d2att - 3|16|13. works absolutely fine. sorry for the long wind but i just want to make sure i give all info before posting my question as i may prevent unness replies. having an at&t phone using tmobile as the carrier, can i use roms intended for t-mobile only, or do i have to stick to at&t/multi-carrier roms only?
Honestly making sure you have a T-Mobile put in is all that matters. Other than that they are fairly interchangeable.

I have been making roms, from Canada claro i747m, and tmobile t999 and att 747 and they all work as they should. no problems at all, using stock att modem i747ucdlk3 without any issues...
all I did was change the build prop to represent d2att..
I have simplemobile which is a tmobile company.. except for now I just used up my 4g.. I usually get 3g, but for some reason im getting an E which speed is like 2g edge.. slow at the moment.. never seen that in 3 months..
check my signature, for my roms... they r all stock original roms..
I'm in the same situation as the op. I have at&t i747 unlocked to use with tmobile. My question is, if I flash a multi-rom What carrier do I choose during the aroma install? do I pick tmobile because thats what network im using now or do I pick at&t because its originally an at&t device? any help or advice would be greatly aprecciated.
during the install of liquidsmooth i chose att since i do have the branded phone. i cant use the lte settings for network cause tmob doesnt have their lte out yet (soon to drop), but i am wanting to try the tmobile install and see if i get any difference in data speeds. other than that, liquidsmooth is a pretty solid build. this is the only rom i have tried on my gs3 so far. id like to try others to maybe help give feedback for builders, i just wasnt sure if i could use tmobile or had to stick to att roms. thanks for the info.
on a side note, the rom unlocked a 1080p video record and i like showing ppl the OC ability. 1.9Ghz. YAY!!!
when I first made my Canada Claro rom d2can everything worked out the box. the only thing was it was showing me info of I747m, everything was still working, same when I made my tmobile rom, it was showing d2tmo, everything worked out the box, just that it showed me info of T999, so both of the roms worked, all I did was change the build prop to represent d2att ATT info..
So the answer is yes, u can use other roms... just be careful not to install the modem. I never changed that. I remove them from the rom.
Danger,, I tried making the international GT I9300 and removed the modem, changed the build prop.. almost bricked my phone, played with it to try to make it work, It would hang and sometimes not boot up... so stay away from international one.
so if u try Canada or tmobile u should be safe, its the same phones... or if someone post roms that are ported to att i747.
I am using i747 for T-Mobile.
Can somebody tell me what ROM i should use in order to get WIFI Calling on it ?
Thank you.

[Q] Which model S4 do I have? (seriously)

I feel dumb for even asking such a rudimentary question, but here's the situation.
I bought an S4 from someone. There's an AT&T logo on the back (cover theoretically could have been replaced, who knows). He had Wicked v5 ROM on it when I bought it. The ROM said the phone was an SGH-M919 so that's what I've assumed. It was a T-Mobile ROM (had WiFi calling option etc). He was on AT&T Straight Talk, gave the phone to me, I popped in my AT&T SIM card and was ready to roll. That initially tells me the phone's SIM-unlocked.
Now I ditched AT&T and switched to Metro PCS. It wouldn't take the SIM until I unlocked the phone. (Metro PCS is on T-Mobile network now, so if the phone WAS a T-Mobile phone, it should have taken the SIM naturally with no problem). Also ODIN recognises it as a SGH-i337, which is the AT&T version and it refuses to flash the T-Mobile stock firmware tar.md5 file to the device.
So it seems I have the AT&T version after all.
Basically..... can the firmware lie and tell me anything it wants to? Which device do I actually have? I'm having trouble connecting to the Metro PCS 4G network locally and can only pick up Edge, so that's why I need to get the right ROM on my phone (to rule out all other possible problems of why it's not working.)
Thanks.
Sounds like an att phone unlocked to t mobile. Pretty sure you could use t mobile firmware

I've figured out it's the SGH-i337 just as you predicted. The T-Mo firmware ran just fine up until I popped the Metro SIM in... unlocked it, worked fine. I wouldn't be complaining one bit.. BUT.... now I can't access the 4G network, only Edge. Running off T-Mobile's towers. I was 30 miles from home last weekend and picked it up for a little while so I know I *can* get it, but not around my home. Other Metro users are getting it. Strangest thing.
I'm in the process o getting a i337 (heh) ROM on it right now and maybe with the Metro SIM in it will properly pick up the 4G around here.
Thanks though, you were right about the model
Take the battery cover off and look for m919 or i337 on the back of the phone,indented or outdented on or in the plastic somewhere.

Settings/More networks/mobile networks
Your Network mode should show LTE,WCDMA (auto connect)
if not, tap on the network mode and select the LTE/WCDMA (auto connect) option and back all the way out.
Turn on airplane mode for about 30 seconds and then turn it back off and see what your results are.
You need to be SURE that LTE reception is possible where you are trying this. After all, no matter how good your hearing is, you won't hear me talking if you're out of earshot, right? LOL
Good luck!
Yeah I've tried it and for some reason I don't have this option but your right about checking if the lte is available before doing anything

If using a build prop mod you can lose your LTE settings in "networks".

Thats strange, this issue has been encountered with rooted phones running stock/custom roms while running some mods.
You may have to do a factory reset, or stop by a TMOBILE store and let them check it out.

Could be that it doesn't support LTE from your carrier.. I think it may be capable to support LTE but its disabled on that model.. I've seen people flash M919 modems and gotten LTE to work. Just make sure you do some research, and more research if you device to do this

I've been rooting my phone as if it was a normal t-mobile m919 but I tried searching for into to see it there was a way to simply make my V (m919V) disappear and solve all my problems but nothing yet I know you can but as far as warranty, brick and risks go I have not found much information regarding this issue and that why I started this post
I wanted to say thank you to everyone for your help and suggestions
OK I've done some research and it seem that the m919v has the lte hardware to run the frequency 700
( http://www.morecellphone.com/compar...vs-samsung-galaxy-s4-lte-gt-i9505-64gb/340724)
And that virgin mobile (bell's network)
(bell is one of the biggest telecommunications companies in canada)
has this frequency on their network
(http://en.m.wikipedia.org/wiki/List_of_LTE_networks)
The only thing is that the lte frequency off 700 was lunched in Ontario last month and I'm in Montreal
But the fact that t-mobile only has 1700 and that virgin uses this here means that the phone isn't the problem and with this information, i've concluded that it a software issue
